METAL LATH SLITTING PRESS Filed April 20, 1929 3 Sheets-. Sheet 3 I Invenron W/TNEssEs:-- BY I Ix M l ql ATTORNEY Patented Sept. 20, 1932 l rm-[TED STATES WILLIAM G. GORYELL, OF YOUNGSTOWN, OHIO METAL LATE SLITTING PRESS Application filed. April 20,

This invention relates to improvements in metal lath slitting punch presses of the type in which a continuously rotating power shaft is designed to produce intermittent rotary I motion of feed rollers employed to deliver sheets to be slitted by the slitting elements of the press. The object of the present improvements is to provide a novel arrangement of levers for transmitting motion from the 10 power shaft to the feed rollers whereby, with minimum power applied to the power shaft and at any given rate of speed thereof, maximum feeding movement of the rollers with ample force to accomplish their function may be obtained, thus to secure maximum production in a minimum amount of time and with the consumption of minimum energy.

With the foregoing general purpose in View, the invention consists in the novel fea-, tures of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.

In the drawings, wherein like characters of reference denote corresponding parts in the different views:

Figural is a side elevation of a metal lath slitting press having the present improvements in one preferred form embodied therein Fig. 2 is a front elevation of the press. Fig. 3 is a side elevation showing the levers in a different position from the position they occupy in Fig. 1; and V Fig. 4 is a view partly in elevation and partly in section of the levers shown in Fig. 8. Referring to the drawings in detail, A designates generally a metal lath slitting press of conventional design, including in its organization a frame 10, a power shaft 11 and feed rollers 12. In accordance with common practice, the power shaft 11 is disposed horizontally and mounted in suitable bearings in frame 10' near the upper end thereof for continuous rotation in any suit able or desired manner as, for-example, by means of a suitably driven endless steel belt ,paratively easy for the latter.

rollers 12 are mounted on shafts 15 journaled in the frame near the lower end thereof, one pair of said rolls being disposed at the front and another pair at the rear of the press. Endless steel belts are preferably used because the drive is vertical, and the shafts of the motor and the press are arranged on short centers, both of these features being difficult for other belting than steel belts, but com- Feed rollers 12 are adapted to be rotated intermittently by power derived from the continuously rotating power shaft 11 and to this end, in accordance with the present in vention, a driving connection, designated genralityof'cooperating levers, is provided between said shaftll and said rollers 12 whereby this purpose is accomplished.

In detail, connection B is inclusive of a pair of levers 16 and 17,'the former of which is pivoted intermediate its ends as at 18 to the frame 10 and the latter of which is of the three-arm or of inverted T-shape type and also is pivoted to said frame, at the junction of its arms, as indicated at 19.

One feed roll shaft 15 of each pair of such shafts has fixed thereto a ratchet wheel 20,

the shafts of each pair being operatively connected together by pinions 21, and the two lower, substantially alined arms 22, 22 of the lever 17 are provided with spring pressed pawls 28, 23, respectively, cooperating with said ratchet wheels, respectively, whereby oscillation of said lever 16 is effective to pro duce intermittent rotation of the respective pairs of feed rolls to effect step-by-step feed of a sheet of material to be slitted, through the press.

ing effected by slotting one of said arms, the v arm of lever 16 in this instance, as indicated at 25, mounting a block 26 in said slot for sliding movement and journaling a pin 27 carried by the other arm, in this instance the arm2l, in said block.

The end of the shaft 11 opposite to the end thereof on which thefiy-wheel 14, is mounted,

- said lever to be raised or lowered. In an event it is manifest, due to the provision and to the general arrangement of theparts-ef tent rotation to said feed rollers, a rotatable power shaft, a second lever pivoted intermediately and operatively connected at one end with said power shaft whereby continuous rotation of the latter oscillates said second mentioned lever, and arconnection between the other end of said second mentioned lever and the third arm ofsa'id first mentioned lever whereby oscillation of said second mentioned lever oscillates said first mentioned lever.
